26 Building and running Gorad
27 --------------------------
28
29 To compile and run Gorad, all the Geant4 envir
30 properly set. Use the shell script in the Gean
31 Compilation of Gorad requires cmake and make s
32 Geant4 itself.
33
34 $ source $G4INSTALL/bin/geant4.(c)sh
35 $ cmake .
36 $ make
37
38 To run Gorad in interactive mode,
39
40 $ ./gorad
41
42 and then, in the keyboard input field, type
43
44 /control/execute <macroFile>
45
46 The user may also use any UI commands shown in
47 Qt window.

49 To run Gorad in batch mode,
50
51 $ ./gorad <macroFIle>

85 Known warning messages while processing a GDML
86 ----------------------------------------------
87
88 If the input GDML file uses some material name
89 these names are unrecognizable by the GDML per
90 warning messages. For example

92 G4GDML: VALIDATION ERROR! ID attribute 'G4_AIR
93 never declared at line: XX

95 These messages are harmless and these material
